• The inhibition of the corrosion of aluminium in hydrochloric acid solution by some 4-(<I>m</I>-Substituted phenylazo)pyrazoles has been studied by three different techniques. The inhibitor efficiency calculated from the three techniques are in good agreement. The corrosion rate is a function of temperature, concentration, and nature of the inhibitor. The inhibitors appear to function through general adsorption following the Langmuir adsorption isotherm. Thermodynamic parameters for adsorption of inhibitors have been calculated and discussed.
